coq_makefile [subdirectory] .... [file.v] ... [file.ml] ... [-custom
  command dependencies file] ... [-I dir] ... [-R physicalpath logicalpath]
  ... [VARIABLE = value] ...  [-opt|-byte] [-f file] [-o file] [-h] [--help]

[file.v]: Coq file to be compiled
[file.ml]: ML file to be compiled
[subdirectory] : subdirectory that should be \"made\"
[-custom command dependencies file]: add target \"file\" with command
  \"command\" and dependencies \"dependencies\"
[-I dir]: look for dependencies in \"dir\"
[-R physicalpath logicalpath]: look for dependencies resursively starting from
 \"physicalpath\". The logical path associated to the physical path is
 \"logicalpath\".
[VARIABLE = value]: Add the variable definition \"VARIABLE=value\"
[-byte]: compile with byte-code version of coq
[-opt]: compile with native-code version of coq
[-impredicative-set]: compile with option -impredicative-set of coq
[-f file]: take the contents of file as arguments
[-o file]: output should go in file file 
[-h]: print this usage summary
[--help]: equivalent to [-h]\n";
